Summary

CVE-2026-7279 is a high-severity Uncontrolled Search Path Element (CWE-427) vulnerability in Org (inferred from references). Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception by PATH Environment Variable (T1574.007); ranked at the 2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to CM-6 (Configuration Settings) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-7279 is a DLL hijacking vulnerability (CWE-427) in AVACAST, software developed by eMPIA Technology. Published on 2026-04-28, it enables authenticated local attackers to place a malicious DLL in a specific directory, which the software then loads, resulting in arbitrary code execution with system privileges. The vulnerability carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high impact with low complexity and requiring only local access and low privileges.

Local authenticated users can exploit this vulnerability by dropping a malicious DLL into the targeted directory that AVACAST searches during its execution. Upon loading the DLL, the attacker achieves arbitrary code execution at system privilege level, potentially allowing full control over the affected system, including data theft, persistence, or further lateral movement.

Advisories from TWCERT/CC provide details on mitigation, available at https://www.twcert.org.tw/en/cp-139-10885-02d83-2.html and https://www.twcert.org.tw/tw/cp-132-10884-f9c21-1.html.

Mitigating Controls (NIST 800-53 r5) AI

Establishes restrictive configuration settings that can define and lock down approved search paths.

Enforces approved authorizations so that only intended actors can place or modify elements in the search path.

Limits privileges so unintended actors cannot write to or control directories in the product's search path.

Restricts logical and physical access to change system configuration, including search-path settings and directories.

mitigates

Restricting software installation reduces the chance that an attacker-controlled path element is introduced into the search path.

mitigates

Secure system architecture and engineering principles require explicit control over search paths and resource locations.

prevents

Secure coding practices directly address the use of fixed or controlled search paths that can be influenced by unintended actors.

finds

Security testing can detect uncontrolled search-path issues but does not prevent them by itself.

prevents

Configuration management can enforce approved search-path settings but does not inherently prevent the weakness.
